Flannel for Docker Overlay Network
Weave: Network Management for Docker
Docker Multi-host Overlay Networking with Etcd

Weave is developed by Weaveworks for developers to control and observe Docker containers network. Similar to Flannel, Calico and Docker Overlay Network, Weave handles Docker multi-host networking and management which can merge network of Docker’s laying on different hosts. Compared with the rest three solutions, weave provides more features and choices. I will write another blog to compare these four solutions in details. In this blog, I will focus on Weave’s install, features and technology ins

In previous post, some overlay network technologies for Docker are analysised. On this post let’s focus on Flannel, a virtual network that creates subnet work Dockers across different hosts.
Introduction to FlannelFlannel, similar to Calico, VXLAN and Weave, provides a configurable virtual overlay network for Docker. Flannel runs an agent, flanneld, on each host and is responsible for allocating subnet lease out of a preconfigured address space. Flannel uses etcd to store network configurations.

L2TP+IPSec is another way to setup VPN on a VPS. L2TP consumes 1701 TCP port to maintain connection and 500/4500 UDP to transfer data. It’s very easy to implement L2TP and IPSec on a Ubuntu 14.04 server.
Before setting up L2TP/IPSec environment, you need to enable PPP support for VPS. See details on section “Enable PPP Support of VPS” of my previous post “Setup PPTP Server on a VPS“ to enable PPP support on RamNode VPS.
When I first installed xl2tpd and openswan, it occured to me the following e
